Title: Vulcanization of rubber
IPC: C08K5/32
Filed: 1932-10-11
Abstract: The hardness and bending strength of high-loaded rubber stocks containing an ultra or semi-ultra accelerator are enhanced by the addition to the mix of a relatively small amount of a cyclic, heterocyclic or substituted cyclic mono-carboxylic acid.  This addition also assists vulcanization.  The preferred additions comprise a halogen- or nitro-substituted benzoic acid and furoic acid.  Active accelerators mentioned are mercaptobenzo - thiazole, zinc dimethyl-dithiocarbamate, the reaction product of mercaptobenzothiazole and diphenylguanidine, butyraldehyde-aniline condensation products and tetramethylthiuram disulphide.  Heavily loaded stocks according to this invention comprise those containing a loading of at least 50 volumes per 100 volumes rubber.  Specification 196,924, [Class 70], is referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of the above combination of acids and active accelerators in rubber mixes which are not heavily loaded, for the purpose of obtaining vulcanization without scorching.  This subject-matter which was illustrated by examples, does not appear in the Specification as accepted.

Abstract: 1462850 Toothed gearing; variable-speed gear; swash-plate gear R DAVIDSON Jnr 27 Dec 1973 28924/76 Divided out of 1462061 Headings F2Q F2D and F2K In a speed-reducing transmission of the kind in which a nutating gear 44, Fig. 2, meshes with a rotor 43, the effective circumference of the gear 44 being, due to its obliquity, greater than that of the rotor, the numbers of teeth on the two members are in proportion to the ratio between the effective circumferences. As shown, the gear 44, prevented from rotating by studs 56 engaging slots 57 in a casing 40, is mounted on an inclined bearing 58 on an input shaft 45 and backed by an inclined face 48 of a sleeve 47 keyed to the input shaft. The rotor 43 is secured to the output shaft 42. The apparatus may be modified by arranging for the casing 40 to be rotatable and extending the studs 56 through the casing so that they are engageable by rods or other mechanical linkage. The apparatus then has four input/output means, one of which is constituted by the reciprocating studs 56, and can be used to convert rotary to reciprocating motion or vice versa and/or as a differential speed-varying device. In a modification, the nutating gear 60, Fig. 4, is rotatably mounted on a shaft 61 and is toothed on both sides for engagement with two rotors 65, 70 either or both of which may be subject to a variable loading to provide differential action. Alternatively, only one rotor may be employed and rotation of the gear 60 may be controlled, e.g. by a friction brake. In a further embodiment the wobble plane 90 of the nutating gear 84, Fig. 6, is offset with respect to the median plane of the gear and the latter coacts with a toothed stator 83 and a toothed rotor 80.

Title: Improvements relating to telephone and like electric signalling systems
IPC: H04B3/20
Filed: 1935-07-19
Abstract: 460,178. Two-way transmission. JONES, C.E.P. July 19, 193o,No. 28945/36. Divided application. [Class 40 (iv)] An arrangement sensitive to the direction of signals through a hybrid coil comprises connections to one of the branches of the 4-wire circuit, e.g. the " return " path, and to one of the other branches, e.g. that to the balancing network FBN, the signal voltages tapped off from these connections being rectified at CR1, CR2 and combined to give a direct-current voltage dependent in direction on which of the tapped-off voltages is the greater. The invention is applied to a system in which the " go " branch is normally blocked by an attenuator AN but is rendered operative on the arrival of speech by a rectifier FTR which is insensitive to low-amplitude noise-currents. The directcurrent voltage derived from the connections to the hybrid coil FHC is applied to two rectifiers MR, RM in opposition and the potential difference across one of these RM is applied to a valve V2 in the input circuit to the rectifier FTR. For speech over the " go " path, the signals in the network FBN are the greater and the voltage across RM. is negligible, but for signals over the " return " path the voltage produced across RM blocks valve V2 to prevent speech which may leak round the other hybrid from rendering the " go " path operative. In a modification, Fig. 2, in order to compensate for the varying impedance of the line L for different connections, the voltage tappings are made to a dummy hybrid coil DHC at which perfect balance between a dummy two-wire line and a dummy network DBN may be obtained.
